IMPROVEMENT IN PRESSES FOR CHARGING ROCKETS.

Specification forming part of Letters Patent No. 40,042. dated September 22, 1863; antedatcd April'22, 1863.

To all whom it may concern:

Be it known that I, J. BURROWS HYDE, of the city of Newark, county of Essex, and State of N ew Jersey, have invented certain Improvements in Presses for Charging Rockets, being also adapted to other uses; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings and the letters of reference marked thereon.

Rocket composition is driven or rammed into the cases by blows from a hand-hammer, a drophammer, also by a lever, by a screw, and by hydrostatic presses, according to the size of the rocket and facilities of the opera-' tor. For war-rockets iron cases are used, and these are loaded under a force so great as to require protection to the case to prevent its being broken or burst by the pressure. This is avoided by placing the case in a mold (of brass generally) made in two parts'and held together by strong iron bands. The mold is then placed under the press. Aquantity of the composition is then put in the tube or case; then a rammer of iron fitting the inside of the case is placed on the composition, when the press is put in action. After the pressure has been given, the rammer is withdrawn, a sec ond charge is added, and the operation is repeated until the case is loaded, when it is re moved from the mold and another case is substituted. It will be seen that by this usual system several manipulations and much time will be saved by the use of my improvement.

The nature of this invention (see drawings, Figures 1 and 11) consistsin constructing apress with but three standards, ties, or uprights, an, a, which take into strong iron headings b and c, that complete the frame. \Vithin this irame the pressure-platen e is fitted to take against and be guided against each of the standards a a a, one of which, a, I employ through the agency of a collar, 9, as a center and carrier of a rotating'table, f, a portion of which eX- tends upon and nearly across the platform 6 within the press, but the greater part of its surface extends beyond and outside the frame of the press, as seen in Fig. 11, which is in part a horizontal section. In the upper surface of this table f several recesses, h h, are shown, and intended to receive as many rocketmolds i t by their flanges Z Z, two of which are shown, with their straps k k and rammers m m, placed in the tubes or cases a a. By this plan only one mould can' be inside the press-frame at one time, the other molds being outside the press, where they may be charged, removed, and replaced while the press is at work, and be ready to be turned under the press as soon as the mold justcharged has been relieved from pressure, and the height clear for the next rammer-head, when the pressure is at once put on again for its work.

At 0 0 0 sliding bolts or pins are placed to hold the flanges of the mold, and at similar contrivances are fixed to hold the rammerhead. The object of these stops is that at times the rammer may be too pinched in the case to be removed by the hand, in which event these bolts 0 and p are brought to bear.

In the drawings I represent a press with three bars or ties, and also actuated by hydrostatic pressure, the cy cut away, while the piston is shown resting against the platen 6; but it will be evident that I can employ but two bars, and forthe pressure can use a lever, screw, or eccentrics, but with less advantage when much power is needed.

YVhat I claim, and desire to secure by Letters Patent, is

Employing one of the bars or ties of the framework of a condensingpress as the axis or journal for a rotating working table or platen, for supporting or carrying the work to be acted on by the press, and arranged in the manner and for the purpose specified.
